the city's mayor whaley said they spoke by phone sunday night. she told the president he is welcome but she made it clear she expects something to be done about gun violence. >> i talked to him about 24 seconds, that he reached that much havoc with that type of gun. i said, i'm from southern ohio. people have rifles and handguns. we're not east coast or west coast folks that say no guns at all. i said, but like i don't understand why anybody, why any citizen would need that gun. and he didn't disagree with me. maybe he was placating me, i don't know. but i appreciate he listened to me around that. we'll continue to push because i don't want other cities to go through this. >> reporter: cnn's ryan young has more from dayton.
